PACHYCEPHALOPSIS FORTIS.
Grey-throated Thickhead.
Pachycephala fo r tis , Gadow, Cat. Birds in Brit. Mus. vol. viii. p. 369 (1883);
W e have already had the pleasure of figuriug two species o f Packycephalopsis in the present work, and we
now introduce to our readers a third very interesting species, recently discovered by Mr. A. Goldie during
his explorations at the back o f the Astrolabe range o f mountains in South-eastern New Guinea.
The present species is somewhat allied to P . hattamensis, but is strikingly differeut, being distinguished
by the uniform grey throat and breast, the pale yellow under tail-eoverts, and the absence of rufous on the
wings. It resembles the last-named species, however, in its olive-green back and grey head.
The following is a description o f the type specimen in the British Museum
Adult. General colour above olive-greenish ; wing-coverts like the back, the greater and primary-coverts
dusky, externally edged with olive-green, the bastard-wing feathers g r ey ; quills dusky brown, externally
olive-green, browner on the primaries, the inner secondaries entirely like the back; tail-feathers dull olive-
brown, greener on the edges and barred with dusky under certain lights ; head and nape slaty grey, as also
the sides o f the neck, ear-coverts, and sides o f fa ce ; lores greyish white; cheeks, throat, and breast pale
grey, with narrow dusky shaft-streaks to some o f the feathers o f the fore neck ; abdomen creamy white;
sides of body pale brown washed with oliv e; thighs ashy washed with olive ; under tail-coverts yellowish white
